my car is a 02 z28 ls1.... no suspension mods at all... damn near stock..

everytime i start my car, after 3-4 mins of driving it the tcs light, abs inop light, and brake light comes on.. and it stays on until i shut the car off.. the brakes work fine, it stops the same way it did before those lights came on.. i just dont have traction controll and abs... what could be the problem?

Is the car a 6spd? Everytime I turned mine off the light came on. I think if you have cruise controll, you dont have TCS (I remember reading something about that when I was changing my tb. I think the cruise controll cars have dual throttle cables or something) Maybe it has been tuned to stay off? As far as the ABS, I had the same light on mine and didnt care. Never got into a major accident so the air bags didnt deploy, so I didnt know if there was something wrong with them or not.

Sounds like a wheel speed sensor/hub assembly is failing. Go somewhere and have them check for a history ABS code, or any ABS codes.

i think i could have excess build up of small metal debris around the magnetic pick-up which is located within the backing plate behind the rotor on the rear end. thats like a common problem for guys that have the same problem as me... seems like my abs electronics arent getting the right pulse signals?? ill check it out tomorrow. thanks for the help though..
